So you can take that idea and compute a different result, does the speed of light imply a max separation (!!!). Assuming speed is linear with distance (just go with it so we can calculate it :-)), then that suggests a maximum size of the universe away from us! It's not that much farther, 13.97 billion. (13.97 billion / 3.26 million * 70 = ~300km/sec). But looking at the other posters comments, we could be moving away from someone at 2c, because if we were both moving at the speed of light in opposite directions the relative separation speed would be 2c, even though each is only moving at c in a different direction from an observer. Is that right? so maybe it's ~28 billion.
